   This issue might be a duplicate of existing issues. Please check:

   • [FEATURE]: Provide a default pre-approved temp directory for skills/tools writing outside the workspace #48100: Requests a pre-approved, per-user temp directory for skills/tools — covers very similar ground (isolated temp space per project/session, avoiding permission prompts for temp writes)
   • [FEATURE]: Handoff skill — save to project directory instead of global temp #36381: Requests project-scoped temp/handoff directories instead of a shared global temp path

   If your request is distinct from those, feel free to clarify the differences so maintainers can better scope this.

   Beyond that, the /tmp/opencode pattern will fail when multiple users use opencode on the same system (/tmp/opencode won't by writable by user B's opencode if it was created by user A's opencode). A simple solution like /tmp/opencode-${UID} would mitigate this. This is what claude does.

   Alternatively, instead of a UUID for the project, an idempotent/stable hash might also work.

   For example:

   • Project dir: /home/behrangsa/Projects/foo
   • Hash: echo "/home/behrangsa/Projects/foo" | sha256sum -> db823db54587807dc5599efbc293ebffdc08bf43feae923a98d54a9df5274b11
   • Temp dir: /tmp/opencode-db823db54587807dc5599efbc293ebffdc08bf43feae923a98d54a9df5274b11/
   • Session dir: /tmp/opencode-db823db54587807dc5599efbc293ebffdc08bf43feae923a98d54a9df5274b11/{session-id}/

   We should anyway be using a subdir of $XDG_RUNTIME_DIR on Linux systems. Similar rules should apply to other systems. Putting it in a system-wide folder is naive.

   My workaround that I put into a comment elsewhere is an alias in my shell: alias opencode=TMPDIR=${XDG_RUNTIME_DIR} opencode

   I suppose you could change that to choose a hashed subfolder of that XDG_RUNTIME_DIR path. Either way, it's sub-optimal that this isn't there already.
